Before this commit:
`--minimal=true` create project without any testing frameworks and disable e2e, lint, test targets.
But, if in this minimal project we try command `ng generate class|component|directive|guard|module|pipe|service`, it will always create `*_spec.ts` files.
After this commit:
`--minimal=true` override `@schematics/angular` in `angular.json` to not create `*_spec.ts` files when using `ng generate *` commands.
